PAPER-PULP MACHINE.

SPECIFICATION forming part of Letters Patent No.V 229,201, dated .Time 22, 1880, Application filed February 28, 1880.

To all 'whom it may concern:

Be it known that I, JAMES TAYLOR, of Luzerne, in the county of Warren and State of New York, have invented certain new and useful Improvements in Paper-Pulp Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it fappertains'to makeand use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. v

This invention contemplates improvements n pulp engines or machines; and it consists in the construction and arrangement of means for conducting the material acted on by the beaters between the parallel saturating or steam chests; in the employment of beaters hun g above rou ghened or corrugated beds, with upward inclines at their rear ends and downward inclines at their forward ends; in the employment of an agitator or feedi n g device on a revolving shaft hung above a downward ineline, and arranged with relation to the beaters and their beds, and of a vertically-adjustable foraminated or-perforated tube located in line with the outlet, substantially as hereinafter more fully set forth.

In the annexed drawings, which fully illustrate my invention, Figure lis plan view with the cover removed of my improved pulp-machine. Fig. 2 is a vertical longitudinal section thereof with the cover in position. Fig. 3 is a vertical transverse section of the same with the screen-tube in position, and Figs. 4. and 5 are detail views of the machine.

Like letters of reference indicate like parts.

The object of this invention is to manipulate and disintegrate libers from Wood or straw, and to soften and mix the fibers obtained from Wood or straw with rag stock or pulp for Manila or liner grades of paper.

A represents a vat or tank of any desired form, having at its top and bottom the outward-extending flanges a, on which v:rest the top and bottom, and between which and said flanges is interposed suitable steam-packing.

B represents the top, which' may be made in hinged sections, as shown, or in any desired manner, and on which may be placed a suitable hopper, to admit of the material being placed in the vat.

C represents the bottom, having the outlet b and the inlets c for the steam to the steamchests.

D represents projections on the outer sides of the vat, said projections being provided with screw threaded opening d to receive a screw-threaded rod, e, which rests against a shaft, E, and admits of the ends of the same being adjusted u p or down.

E represents the main shaft, working in steam tight sliding boxes fj' fj', and provided on either end with band-wheels g g for imparting to it the necessary motion.

` F represents cylinders rigidly attached to the shaft E. These cylinders are ribbed or Otherwise roughened in order to more perfeet-ly act on the material.

G represents the beds, between which and the cylinders the material passes. Said beds are ribbed or otherwise roughened to correspond with the cylinders.

The shaft E, carrying the cylinders F, is allowed to rise and fall `to accommodate itself to the amount of material between the cylinders and beds by means of the sliding boxes.

H represents a shaft passing through one end of the vat, and having upon either end th packing-boxes h and band-wheels t.

I represents the agitator, which may be toothed or of any other desired construction. Said agitator is rigidly attached to the shaft H, and receives its motion from it.

K K represent steam-chests, through which passes the main shaft E.

L represents a steam-chest of triangular form, situated in one end of the vat. Said steam-chest has its sides t" i slightly curved, and is to be provided, as also are steam-chests K K, with suitable openings to admit the steam into the tank.

M vare inclines leading to the beds G. N are inclines leading from the same.

O represents a curved incline in one end of the vat, just in the rear of the agitator, to enable it to more easily catch and move forward the material to the cylinder.

l? represents a screw-cap over the outlet.

Q represents a shaft extending from the outlet up through the top of the vat, and hav- IOO ing on its upper end a roller, l. Said shaft is supported by a suitable frame-work, m.

.R represents a wire screen surrounding the shaft Q, and having attached thereto the cords n, whereby it may be raised or lowered at will.

The screen R is notv used in unsteamed pulp, and can be drawn up out of the way; but for pulp that has been steamed or ehemicalized and bleached the screen can be lowered down in place after the lime, chemicals, and steam have done their work.4 The object of the screen is to drain off from the wood or other pulp all the dirty water and lime or other ingredients that must be washed out of the pulp before it is beaten for the paper-stock.

Hot or cold water is letinto the vat andthe cylinders are raised and set in motion, as also is the agitator, which will wash the stock, and by the aid of the wire screen the stock can be kept in the vat and the dirty water, Snc., run olf. By washing sawdust, wood, or chips in this manner the stock or pulp is lnade cleaner and whiter. V

The operation is as follows: The material to be converted into pulp is placed into the vat. The agitator moves the same forward between the beds and cylinders, which carry it out to the opposite side. sides of the steam-chest L back between the steam-chests K, which act as guides, to the agitator, which again sends it forward, and the operation continues until the material is in the desired state. A

During the operation steam is let into the vat, which renders the process of disintegrating more perfect.

Instead of the steam-chests K, steamcoils may be used.

It will be seen that I have shown a tank with a flat covering with bolts, so that steampacking maybe introduced between the top and body; but the main shaft may be mounted on the top of the tank and a suitable circle provided to cover the cylinders, as desired.

1t will be further seen, that the engine being steam-tight, straw cut and put into the tank with a proper quantity of lime and the'steam It is then guided by the curved Y let onto the stock from the steam-chests, the

samecan be prepared in a very short time.

By this arrangement sawed, chipped, or crushed wood, shavings, or sawdust can be manipulated and softened to be refined suitable for the manufacture of paper.

Although I have described a steam-tank, yet the manipulation can be effected without the use of steam, but simply with cold water.

Having thus fully described my invention, what I claim as new, and desi-re to secure by Letters Patent, is

l. The vessel A, having the corrugated or roughened beds G, provided with downward oblique inclines N, and the double concaved or triangular tank L, in combination with the beaters F on a shaft, E, and parallel saturating or steam chests K, substantially as and for the purpose set forth.

2. The combination, with the vessel A, having the concaved or inclined cleat O, beds G, with their rear ends provided with upward inclines M, and their forward ends with ldownward oblique inclines N, and triangular tank L, of the'feeder or agitator U, beaters F, and i saturating or steam chests K, substantially as and for the purpose set forth.

3. The combination, with the vessel A, having an outlet, P, of the foraminated or 4perforated tube R, having vertically-adj usting cords a, or equivalents, passing over pulleys in a supporting-frame over the vessel A, substantially
